Privilege separation in computer programming and security is a technique that divides a program into parts, each with specific privileges needed to perform a task. This method helps to limit the potential damage of a computer security vulnerability by ensuring that any successful attack against the larger program will gain minimal access. Privilege separation can be achieved by distinguishing user IDs, splitting a single program into smaller ones with different file system permissions, or by dropping root under Unix-like operating systems.
